What is Wiring in Arrays?

Prerequisite: Arrays 

Arrays are used to create lists of elements with the same data type and store them in adjacent regions of memory. Arrays are just the grouping of elements of the same data type. 1-Dimensional arrays, 2-Dimensional arrays, and 3-Dimensional arrays are just a few of the several types of arrays that can be declared.

What is Wiring?

Wiring is the concept of visualizing the elements of the array connected, It helps us to visualize the multidimensional into a flattened form.

Wiring in the 2-D Array

An array that can store multiple arrays inside it is known as a 2-D array or 2-Dimensional array. A 2-dimensional array of elements can be accessed the same as a normal array with the help of Indexes. To know more about 2D arrays refer to multidimensional arrays for Java and for C/C++.

Wiring in a 2D array

Visualizing a 2D array as a collection of multiple 1D arrays can be quite easy with the help of wiring. Below is the implementation of the concept with the 2-D array.

Example:

C

// C Program to implement
// Wiring 2D array
#include <stdio.h>

int main()
{
    // Declaration of 2-Dimenssional array in the form
    // of wiring
    int arr[3][3]
        = { { 1, 2, 3 }, { 4, 5, 6 }, { 7, 8, 9 } };

    for (int i = 0; i < 3; i++) {
        for (int j = 0; j < 3; j++) {
            printf("%d ", arr[i][j]);
        }
        printf("\n");
    }

    printf("Wiring:\n");

    // traversing all the elements of wiring array
    for (int i = 0; i < 3; i++) {
        for (int j = 0; j < 3; j++) {
            // printing all elements
            printf("%d ", arr[i][j]);
        }
        if (i == 2)
            break;

        printf(" , ");
    }

    return 0;
}

C++

// C++ Program to implement
// Wiring in 2D array
#include <iostream>
using namespace std;

int main()
{
    // Declaration of 2-Dimenssional array in the form
    // of wiring
    int arr[3][3]
        = { { 1, 2, 3 }, { 4, 5, 6 }, { 7, 8, 9 } };

    for (int i = 0; i < 3; i++) {
        for (int j = 0; j < 3; j++) {
            cout << arr[i][j] << " ";
        }
        cout << endl;
    }

    cout << "Wiring:" << endl;

    for (int i = 0; i < 3; i++) {
        for (int j = 0; j < 3; j++) {
            cout << arr[i][j] << " ";
        }
        if (i == 2)
            break;

        cout << " , ";
    }

    return 0;
}

Java

// Java Program to implement
// Concept of wiring
import java.io.*;

class GFG {
    // Java Program t0 implement 2-D
    // array using concept of wiring
    public static void main(String[] args)
    {

        // Declaration of 2-Dimenssional array in the form
        // of wiring
        int Arr[][]
            = { { 1, 2, 3 }, { 4, 5, 6 }, { 7, 8, 9 } };

        for (int i = 0; i < Arr.length; i++) {
            for (int j = 0; j < Arr[0].length; j++) {
                // printing all elements
                // in the form of matrix
                System.out.print(Arr[i][j] + " ");
            }
            System.out.println(" ");
        }

        System.out.println("Wiring:");
        // traversing all the elements of wiring array
        for (int i = 0; i < Arr.length; i++) {
            for (int j = 0; j < Arr[0].length; j++) {
                // printing all elements
                // in the form of matrix
                System.out.print(Arr[i][j] + " ");
            }
            if (i == Arr.length - 1)
                break;
            System.out.print(" , ");
        }
    }
}

Wiring Related to a 3-D Array

A 3-Dimensional array is a group of 2-dimensional arrays that are successively stored at different locations within the array.

The wiring’s initial purpose was to connect objects, and in a three-dimensional array, it serves the same purpose by connecting the array to create a new three-dimensional structure. The array’s blocks and elements are all interconnected. In this post, we’ll talk about 3-dimensional arrays that are wired together. These three-dimensional arrays in wiring function similarly to an array’s matrix declarations.

        { { 9, 8, 7, 5 },{ 4, 5, 6, 8 },{ 7, 8, 9, 1 },{ 5, 4, 7, 9 } },
